[Leukocoria (white pupil) among children--mother is always right].

Leucocoria is a rare, but serious symptom in early childhood. It may be present at birth or develop during infancy. As in adults, infants usually display a black pupil, and upon shining a bright light into the pupil with the ophthalmoscope, an orange or red reflex emerges. The first person to see that something is wrong, is often the mother, but she cannot give a precise description. When the infant is crying it can be difficult to examine the red reflex, and the necessity of admitting the infant to an ophthalmologist, when the mother is worried, is discussed. In this paper we discuss two cases of retinoblastoma and one case of congenital cataract where the treatment was delayed due to late diagnosis of the leucocoria. The main conclusion is always to listen to the relatives when they are worried about the infant's eye, and to make sure that the infant is properly examined.

Mortality and causes of mortality among cataract-extracted patients. A 10-year follow-up.

PURPOSE: The purpose of this study was to compare the mortality among patients undergoing intracapsular cataract extraction to the mortality in a gender-and age-identical Danish reference population, and to compare the patients' primary causes of death to those in the general population. MATERIALS AND METHODS: We reviewed medical records of patients undergoing ICCE from January 1st 1984 to December 31st 1986 at the Department of Ophthalmology, Aalborg Hospital, Denmark. Information on the deaths of these patients was obtained from the Danish National Population Register. Information on mortality in Denmark was obtained from published statistics. RESULTS: We found an increased mortality among the patients with cataract with an SMR (standard mortality rate) of 1.12 (95% confidence interval 1.02-1.23). The slightly increased mortality was observed for both men and women and for all examined causes of death. CONCLUSION: The slightly increased mortality among patients with cataract may indicate a general deterioration of health for these patients.

Persistent corneal oedema following ICCE. Influence of IOL type.

PURPOSE: To examine the frequency of persistent corneal oedema following intracapsular cataract extraction (ICCE). To examine whether the type of intraocular lens has any influence on persistent corneal oedema following ICCE. METHODS: A retrospective study of 1041 consecutive ICCE operations followed for at least eight years. The cumulative incidence of persistent corneal oedema was calculated for the whole group and compared to the incidence in subgroups defined by type of intraocular lens. RESULTS: The cumulative incidence of persistent corneal oedema following ICCE was 2.3% for the whole group. The highest incidence (10.3%) was found in the group of patients, who received a 3-M style 77 anterior chamber lens while the lowest incidence (1.0%) were found among patients receiving a Choyce anterior chamber lens. Compared to this, the patients who received no intraocular lens showed a frequency of persistent corneal oedema of 1.4%. Among the patients who developed persistent corneal oedema the number of re-operations was higher (27.3%) compared to the patients who did not develop persistent corneal oedema (4.4%). The frequency of preoperative dystrophy was the same whether or not the patients developed persistent corneal oedema. There were no difference in gender, age or other pre-operative data between the two groups. CONCLUSION: After ICCE 2.3% developed persistent corneal oedema. There was a significant difference between the frequencies of persistent corneal oedema depending on the type of intraocular lens from 1.0% in eyes receiving a Choyce anterior chamber lens to 10.3% in eyes receiving a semi-flexible 3-M style 77 anterior chamber lens.

Retinal detachment following intracapsular cataract extraction. A 10-year follow-up study.

PURPOSE: To examine the incidence of and risk factors for retinal detachment during a 10-year follow-up on intracapsular cataract extraction (ICCE). METHODS: Retrospective analysis of medical records of 1041 eyes operated on with ICCE in the years 1984-86. A complete follow-up was achieved, and actuarial methods were used in the risk assessment. The risk time averaged 82 months. RESULTS: Twenty-two (2.1%) eyes developed retinal detachment; half of the cases occurred during the first postoperative year, but new cases emerged throughout the period. The cumulative incidence of RD amounted to 2.8%; 95% confidence interval: 1.5-4.2%. Multivariate Cox regression analysis identified younger age at surgery (relative risk for each 10-year increase in age=0.6; 95% confidence interval: 0.39-0.95) and male gender (relative risk=2.5; 95% confidence interval 1.04-6.04) as significant risk factors for RD. Eleven eyes, 50% of eyes with RD and 1% of the total number of eyes, lost useful vision in spite of retinal surgery. CONCLUSION: Even though the risk for both RD and an unfavourable result following retinal surgery may be smaller using contemporary surgical techniques, the present study indicates a substantial morbidity following cataract surgery, when a sufficiently long observation period is considered.

Persisting corneal oedema following intracapsular cataract extraction.

PURPOSE: The purpose of this study was to reveal the frequency of persisting corneal oedema following intracapsular cataract extraction and at the same time to examine whether the survival rate after penetrating keratoplasty due to this diagnosis differs from the survival rate following penetrating keratoplasty due to primary Fuchs' endothelial dystrophy. METHODS AND MATERIAL: A series of 2455 eyes underwent intracapsular cataract extraction between January 1, 1986 and December 31, 1988, at the Department of Ophthalmology, Arhus University Hospital. The medical files were examined to study the frequency of persisting corneal oedema. Patients with persisting corneal oedema were offered penetrating keratoplasty and the survival rate following this procedure was calculated. RESULTS: The frequency of pseudophakic persisting corneal oedema was 5.3% in the group of patients who underwent intracapsular cataract extraction. The survival of the following corneal transplantation was 54% after 2 years of follow-up. This is a low survival rate compared to the survival rate in primary Fuchs' endothelial dystrophy, but there is a similarity to this disease in a development of a slowly progressive oedema in 17% compared to 13% in primary Fuchs' endothelial dystrophy. CONCLUSION: 5.3% of a group of patients who underwent intracapsular cataract extraction developed persisting corneal oedema within a 5 to 7-year follow-up period. When these patients underwent penetrating keratoplasty the survival rate of the graft was 54% after 2 years of follow-up.

Significant effect of high-resolution HLA-DRB1 matching in high-risk corneal transplantation.

The effect of HLA matching in corneal transplantation is still--after numerous of studies--disputable. We investigated the effect of DRB1 matching in high-risk cases with vascularization and/or retransplantation. Only class II antigens were matched because we were unable to obtain donor lymphocytes for HLA typing. Typing was performed on DNA isolated from the ocular tissues up to 24 hr after death. When this study was initiated, DNA-based methods had been developed only for class II typing. The first part of the study concerns 74 cases with at least 3 years of observation fully matched for 17 DRB1 specificities detected using restriction fragment-length polymorphism. This showed an improved long-term graft survival of 72% compared with 45% in a historical control group of 23 comparable cases. In the second part of the study, stored DNA samples from the restriction fragment-length polymorphism-matched donor-recipient pairs were subjected to retyping with a new method based on sequence-specific polymerase chain reaction. It was possible to split DRB1*01, *04, and *11 in 3, 14, and 5 alleles, respectively. The matching was then re-assigned taking all splits into account. This showed that 36 cases had at least one incompatibility, whereas 38 cases were fully compatible. The long-term graft survival rate was 79% in the matched group compared with only 59% in the mismatched group, which is significantly different at P=0.032. This retrospective, but blinded, randomized study is strong evidence for the effect of matching and may give scope for international collaboration to obtain completely matched corneas for this group of patients.

Recurrence and rejection rates following corneal transplantation for herpes simplex keratitis.

Seventy-two penetrating primary keratoplasties for herpes simplex keratitis performed from 1970 to 1993 were reviewed. Postoperative follow-up periods ranged from 6 months to 16 years with 2 years median. Epithelial herpetic recurrence occurred in 25% of the transplants the first year and in 44% during the first 2 years. Primary allograft rejection was observed in 29% of the grafts the first year and in 46% during the first 2 years. Preoperative inflammation was a risk factor for preservation of a clear cornea (p < 0.10). The degree of corneal vascularization prior to operation did not influence the survival of the grafts. The overall one-year survival rate of a clear graft was 84% and the 2-year survival rate was 67%. Prophylactic antiviral treatment is discussed.

Cataracts in Morquio syndrome (mucopolysaccharidosis IV A).

Three siblings with Morquio syndrome (mucopolysaccharidosis IV A) are described. In addition to the characteristic dwarfism with skeletal deformities, odontoid anomalies, hearing loss and corneal clouding, the authors found almost identical lens opacities in all three patients. Lenticular opacities have not previously been described in patients with Morquio's syndrome IV A.

Retinal detachment following intracapsular cataract extraction.

A retrospective investigation of aphakic retinal detachments following intracapsular cataract extraction during a 12-year period was performed. A total of 8350 eyes had intracapsular cataract extraction in the study period and 118 eyes developed aphakic retinal detachment. The occurrence of retinal detachment is related to age, sex, intraoperative complications, myopia, hyperopia, and pseudophakia. Age and myopia were significantly associated with aphakic retinal detachment. Previous aphakic retinal detachment in the one eye was a strong predictor for the other eye.

Pediplot: A computer-program for drawing pedigrees.

The paper describes a personal computer (PC) program PEDIPLOT for drawing genetic pedigrees. It is easy to use because the input file is created from index cards by a special program PEDI-BASE. The place in the pedigree is calculated from the parents id, which means the order of the persons in indifferent. It is possible to draw rectangular as well as circular pedigrees.
